Abstract
Una nueva y util mejora en el proceso de fabricacion de una sal de ácido carboxílico, particularmente una sal de ácido aminocarboxílico, a partir de un alcohol primario, particularmente un aminoalcohol primario. El proceso de fabricacion de sales de ácidos aminocarboxílicos comprende poner en contacto una solucion acuosa de un aminoalcohol primario con una base fuerte (hidroxido) seleccionada a partir de un grupo formado por un hidroxido de metal alcalino, un hidroxido de metal alcalino térreo, un hidroxido de un compuesto de amonio incluyendo un hidroxido de tetraalquilamonio, o compuestos similares, en la presencia de una cantidad efectiva de un catalizador. El catalizador comprende uno o más de los elementos seleccionados a partir del grupo formado por cobre, cobalto, níquel, y cadmio así como en forma opcional cantidades menores de cromo, titanio, niobio, tantalio, zirconio, vanadio, molibdeno, manganeso, tungsteno, cobalto, níquel, y mezclas de los mismos. La mezcla de reaccion contiene menos de aproximadamente 3000 ppm, preferiblemente menos de aproximadamente 500 ppm, de mayor preferencia menos de aproximadamente 100 ppm de cobre oxidado (Cu+ y/o Cu2+) durante la reaccion. La concentracion de agentes oxidantes en los reactivos debe ser mínima para prevenir la formacion de cobre oxidado a partir del catalizador de cobre metálico.A new and useful improvement in the manufacturing process of a carboxylic acid salt, particularly an aminocarboxylic acid salt, from a primary alcohol, particularly a primary amino alcohol. The process for manufacturing salts of aminocarboxylic acids comprises contacting an aqueous solution of a primary amino alcohol with a strong base (hydroxide) selected from a group consisting of an alkali metal hydroxide, an alkaline earth metal hydroxide, a hydroxide of an ammonium compound including a tetraalkylammonium hydroxide, or similar compounds, in the presence of an effective amount of a catalyst. The catalyst comprises one or more of the elements selected from the group consisting of copper, cobalt, nickel, and cadmium as well as optionally minor amounts of chromium, titanium, niobium, tantalum, zirconium, vanadium, molybdenum, manganese, tungsten, cobalt, nickel, and mixtures thereof. The reaction mixture contains less than about 3000 ppm, preferably less than about 500 ppm, more preferably less than about 100 ppm of oxidized copper (Cu + and / or Cu2 +) during the reaction. The concentration of oxidizing agents in the reagents should be minimal to prevent the formation of oxidized copper from the metal copper catalyst.
